I have a really nice LCD tv but it doesn't have pc input and I would like to use it as a monitor. I have DVI ports on my PC but no way to connect it to the TV. what's the best way to do this? I was thinking a dvi to composite converter but everything I've found is really expensive. I have extra pci ports if a card is needed and as far as I know, composite or component would be an option. S-video might be, I'm not sure (It's my college roommate's tv and I haven't seen it yet). any suggestions?
